Abstract
The utility model relates to a kind of novel blowout preventer, and it comprises housing, cylinder cap assembly, side door, bearing pin, all-or-nothing piece, pole shutoff and flashboard body; Wherein, described cylinder cap assembly is installed on one end of housing; Described side door is installed on the other end of housing by bearing pin; In described housing, be provided with an inner chamber; Described flashboard body is positioned at inner chamber; Described all-or-nothing piece, pole shutoff are connected to respectively on flashboard body.Novel blowout preventer of the present utility model is realized the safe and reliable use of preventer, alleviates operating personnel's labour intensity, increases work efficiency, and facilitates the lifting of Oil Field derrick simultaneously.
Description
[technical field]
The utility model relates to a kind of oil well rig, is specifically related to a kind of novel blowout preventer, and it is higher that it is applicable to working condition requirement, and requires, with the oil field of changing flashboard body, to belong to technical field of petroleum extraction.
[background technology]
In drilling well, completion, well testing or workover treatment, preventer is installed in well head, to prevent the ejection of gases at high pressure in drilling process, liquid and to cause the accident.Because the condition of work of preventer is severe, well is pressed higher, therefore the pressure part of preventer is had to higher requirement.
In flashboard assembly, rubber parts is consumable accessory, needs at set intervals to change flashboard assembly, and common preventer need to be dismantled eight cylinder bolts, has increased like this operator's labour intensity, and spended time is longer.So reduce labor intensity, enhance productivity be oil field in the urgent need to.Meanwhile the little preventer of volume, lightweight because of it, and convenient transport is also more and more subject to the favor in oil field.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of novel blowout preventer, to overcome described defect of the prior art.
[utility model content]
For addressing the above problem, it is a kind of simple in structure, safe and reliable, easy to use and can alleviate the novel blowout preventer of labor intensity of operating staff that the purpose of this utility model is to provide.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of novel blowout preventer, and it comprises housing, cylinder cap assembly, side door, bearing pin, all-or-nothing piece, pole shutoff and flashboard body; Wherein, described cylinder cap assembly is installed on one end of housing; Described side door is installed on the other end of housing by bearing pin; In described housing, be provided with an inner chamber; Described flashboard body is positioned at inner chamber; Described all-or-nothing piece, pole shutoff are connected to respectively on flashboard body.
Novel blowout preventer of the present utility model is further set to: described side door is specially the flange without side door bolt.
Novel blowout preventer of the present utility model is further set to: on described side door, offer a pair of perforation that diagonal angle arranges that is, described all-or-nothing piece, pole shutoff pass described side door by described perforation.
Novel blowout preventer of the present utility model is also set to: the cross section of described inner chamber is long oval structure.
Compared with prior art, the utlity model has following beneficial effect:
1. the housing of novel blowout preventer of the present utility model and side door adopt the flange arrangement without side door bolt, have replaced the form of old-fashioned cylinder bolt locking, only need rotating pin, can realize the opening and closing of cylinder cap assembly.
2. the advantages such as novel blowout preventer of the present utility model utilizes all-or-nothing piece, pole shutoff to be gradient distribution, is convenient for changing flashboard body, effectively reduces the volume of preventer simultaneously, realizes preventer weight saving, transports, easy for installation.

[detailed description of the invention]
Refer to Figure of description 1 to shown in accompanying drawing 5, the utility model is a kind of novel blowout preventer, and it is assembled by several parts such as housing 1, cylinder cap assembly 2, side door 3, bearing pin 4, all-or-nothing piece 5, pole shutoff 6 and flashboard bodies 7.
Wherein, described cylinder cap assembly 2 is installed on one end of housing 1; Described side door 3 is installed on the other end of housing 1 by bearing pin 4.
Described side door 3 is specially the flange without side door bolt, and it has replaced the form of old-fashioned cylinder bolt locking, and needs rotating pin 4, can realize the opening and closing of flashboard assembly.
In described housing 1, be provided with an inner chamber 8, the cross section of this inner chamber 8 is long oval structure, and the design verification of this shape by finite element analysis and in repeatedly using, can ensure that the peak stress that inner chamber 8 bears is more even, makes sealing performance reliable.
Described flashboard body 7 is positioned at inner chamber 8.Described all-or-nothing piece 6, pole shutoff 7 are connected to respectively on flashboard body 7, to control the switch of flashboard body 7.
Further, offer a pair of perforation 9 that diagonal angle arranges that is on described side door 3, described all-or-nothing piece 6, pole shutoff 7 pass described side door 3 by described perforation 9.And be the all-or-nothing piece 6 of diagonal angle distribution, the volume that pole shutoff 7 can effectively reduce preventer, and realize preventer weight saving, transport, easy for installation.
Above detailed description of the invention is only the preferred embodiment of this creation, not in order to limit this creation, any amendment of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
